SASH-FASTEN ER.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed March 1, 1905. Serial No. 247,947.

To all whom, it may concern.-

Be it known that I, GAYLoRD A. ORR, acitizen of the United States, and aresident of Oripplecreek, in the county of Teller and State of Colorado,have invented a new and Improved Sash-Fastener, of which the followingis a full, clear, and exact description.

This invention relates to sash-fasteners, and especially to that classadapted to be used in connection with sliding sashes which may be raisedor lowered in the sash-frame.

The object of the invention is to simplify the construction of suchfasteners and to provide a mechanism which may be operated in a simplemanner so as to hold the sash in an elevated or open position or in alocked condition when closed.

A further object has been to dispense with the use of springs andsimilar parts likely to get out of order.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation showing a corner of a sash to which mysash-fastener has been applied, the said sash-fastener. being shown insection. In this view also a portion of the sash-frame is shown,illustrating the manner in which the sash is supported therefrom, thesash being represented in-an open or raised position. Fig. 2 is avertical section taken substantially centrally through the sash-fastenerand showing a portion of the sash also in section. -Fig. 3 is a viewsubstantially similar to Fig; 1, except that it represents the sash asin a closed and locked condition. Furthermore, in this view the innerconstruction of the fastener is somewhat difierent from that illustratedin Fig. 1. A portion of the sash-frame is shown in section. Fig. 4 is aside elevation showing a portion of the parts shown in Fig. 3, butshowing the mechanism of the fastener and lock in a new relation, thefastener being shown broken away and partly in section, as will appear.Fig. 5 is a vertical section taken substantially upon the line 5 5 ofFig. 3, and Fig. 6 is an elevation of a portion of the sash frame orcasing and showing a face view of the lock used in connection with myfastener.

Referring more particularly to the parts, and especially to Figs. 1 and2, 1 represents the side of a sash-frame in which a sash 2 is placed toslide vertically. The sash 2 is represented in a raised position. Inapplying my invention to such a sash I provide a casing 3 of thebox-like form usually found in the construction of looks or fasteners.Within the interior of this casing is a catch 4, pivotally mounted upona transverse bolt or pin 5. This pin 5 is preferably disposed near theedge 6 of the casing, which edge preferably lies substantially parallelwith the edge of the sash-frame 1, and the wall of the casing at thispoint is provided near its lower portion with an opening 7. The body 8of the catch 4 preferably inclines downwardly from the pivot-bolt 5 andis formed at its extremity with an outwardly-bent toe 9, which protrudesthrough the aforesaid opening 7 and projects into the space near theedge of the sash-frame. The catch is provided beyond the pivot-bolt 5with an enlarged tail or lobe 10, which constitutes a counterweight andtends to maintain the toe 9 in an elevated position, such as that shownin Fig. 1. At the rear edge 11 of the casing 3 the wall thereof isprovided with an opening 12, preferably near its lower portion, andthrough this opening projects a lever 13, the same being pivotallymounted upon a .bolt 14 within the casing, as will be readilyunderstood. Within the casing beyond the pivot-bolt 14 the body of thislever is enlarged, so as to form a shoe 15, presenting an inclined upperedge 16. Against this edge rests the lower edge of the aforesaid tail orcounterweight 10, and the edge of the counterweight is correspondinglyinclined, so that the edges of these two pieces abut each other closely,as shown in Fig. 1.

The fastening device is preferably attached to the rail 17 of the sashnear the lower rail It is secured in position by bolts 19, two beingarranged above at opposite corners of the casing, as shown, and onebelow at substantially the central line of the casing. In order toaccommodate the lever 13 to this position of the lowermost bolt orscrew, the lower edge of the shoe 15 is provided with a recess 20, whichlies around the body of the lower bolt when the movable parts of thefastener occupy their normal positions.

In order to enable the fastener to support the sash in differentpositions in the frame, the side of the frame will be provided atsuitable points with fixed buttons or rests 21, the same being of commonform and presenting inclined lower faces 22 and substantially horizontalupper faces or shoulders 23.

From the construction described above it should now be apparent that ifthe sash is raised when the toe 9 of the catch strikes against one ofthe inclined faces 22 the toe will be forced downwardly, so as to makethe catch occupy substantially the position in which it is indicated indotted outline in Fig. 1. Thus the toe of the catch would move back intothe opening 7, so as to allow it to pass into the space above the rest21. As soon as it had passed, by reason of the counterweight 10, itwould immediately assume its normal position and project into the spaceabove the shoulder 23, supporting the sash in its elevated position, aswill be readily understood. It should be observed that this operation ofthe catch is independent of any movement of the lever 13 and takes placewithout the lever 13 being touched by the person raising the window.l/Vhen, however, it is desired to lower the sash the projectingextremity of the lever 13 may be depressed by ones linger, so as toelevate the shoe 15. The elevation of the shoe in this manner willoperate, of course, to throw the toe 9 backwardly, so as to allow thesame to pass the rest 21.

The construction shown in Figs. 3 to 6 may be adopted. resented asattached to a sash in substantially the same position as before. Theform of the casing 24 is substantially the same as the form shown inFig. 1, the only difference being with respect to the arrangement of theopenings and the arrangement of the bolts for attaching the casing.Also, the mechanism within the casing is slightly altered inconstruction. A catch 25 is mounted upon a pivot-bolt 26 substantiallyas before and it is formed with a projecting toe 27, which normallyprotrudes through an opening 28 in the forward edge of the casing. Therear portion of the catch 25 is enlarged as before to form acounterpoise 29, and the lower edge 30 of the said counterpoise is whenat rest horizontal, as shown in Fig. 3. Just beneath the edge 30 a block31 is mounted upon a pivot-bolt 32, said block having a substantiallyhorizontal upper edge upon which the aforesaid edge 30 normally rests.In Fig. 3 the parts are shown in their normal relation. The body of theblock 31 is of substantially rectangular form, as shown, and its loweredge normally rests against the bottom wall of the casing 24. Beyond thepivot-bolt 32 the block is formed with a projecting ear 33, to which cara link 34 attaches pivotally. As shown, this link depends in the spacebeneath the ear 33, and its lower extremity is bent outwardly, asillustrated most clearly in Fig. 5, so as to present a lip 35, adaptedto be depressed by ones finger to operate the catch. The outer face orwall of the casing 24 is provided with an opening 36, through which thislip 35 projects. As shown in Fig. 4, the width of the lip 35 issubstantially the same as the width of the opening 36, and said openingis of sub- In Fig. 3 the casing 24 is repstantially rectangular form,from which arrangement the side edges of the opening operate as guidesfor the lower portion of the link. At the side of the window-frame 37buttons may be provided similar to the buttons described in connectionwith the other form of device, one of said buttons being represented at38 in Fig. 3. These buttons operate to support the sash at any desiredheight, and their construction is such that they will operate inconnection with the catch 25, so as to allow the catch to pass when thesash is being raised. The mode of operation hence is substantially thesame as that described in connection with the form first illustrated.

hen it is desired to withdraw the toe 27, so as to enable the sash to belowered, this would be accomplished by pressing down the lip Thisoperation effects a rotary displacement of the block 31, the upper edgeof which then raises the counterpoise 29 of the catch, as illustrated inFig. 4, and this throws the toe 27 into the casing, as will be readilyunderstood. In practice the rounded toe 47 would be curved on its underside in an arc struck from the pivot-pin as a center. and the clearancewould be sufficient at the edge 50 to permit the movement indicated.lVith this form of device I prefer to use four fasteningbolts 39,disposed at the corners of the casing, as shown.

1 provide a lock 40, which may be used in connection with either of theforms described above, affording means for locking the sash in itsclosed position. 1 have illustrated this lock in connection with theform of the device set forth in Figs. 3 to 6. In order to apply thislock, 1 form the facing-strip 41 with a recess 42, in which the lock ismounted upon a horizontal pin 43, said pin being suitably supported in aplate 44, attached to the face of the facing-strip, as illustrated. Thebody of this lock is of substantially the form shown, presenting,preferably, a curved lower edge 45, a normally horizontal upper edge 46,and a toe 47, which projects substantially horizontally from a verticalouter face 48. The pin 43 is preferably attached to the lock at a pointvertically above the center of gravity thereof, so that the lock wouldnormally hang of its own accord in substantially the position in whichit is shown in Fig. 3 that is, with the edge 46 in a horizontal plane.This lock projects outwardly from the facing-strip, as illustrated, soas to lie in the path of the forward edge or wall 49 of the casing. When the sash is being moved downwardly to its closed position, the loweredge 50 of the opening 28 will engage the toe 47 and force the same inthe direction of the window-frame, as illustrated in Fig. 4. The lockwill, however, immediately return itself by gravity to its normalposition, and when it returns the toe 47 will lie at the lower edge ofthe opening 28, as illustrated in Fig. 3,

and the lower edge of the toe 27 will be in contact substantially withthe upper edge 4:6 of the look. When the parts assume this relation, itwill evidently be impossible to raise the sash from the outside, and thesash cannot be raised until the lock is swung rearwardly, so as todisengage its toe from the casing of the fastener. The construction ofthe fastener enables the lock to be thrown back in order to disengagethe same in the manner suggested. This would be accomplished byoperating the catch 35 so as to depress its toe 27 from the position inwhich it is shown in Fig. 3. When this is done, the lower edge of thetoe 27 of course depresses the adjacent part of the edge 46 of the lock,moving this edge down so as to rotate the look upon its pin 43, as willbe readily understood. Thus the lock 40 can be moved back intosubstantially the position in which it is shown in Fig. 4:, releasingthe sash and allowing the same to be raised.

I construct the casings of the locks in a way which facilitates theraising of the windowsash. In the form shown in Fig. 1 I extend the.lower wall of the casing at the edge remote from the casement, so as toform a pro jecting hook or finger-hold 51.

With the form shown in Figs. ject a hook 52 outwardly from thecasing,preferably below the lip 35.

It will be seen that in both forms the hooks or finger-holds are locatedin a position conveniently reached while operating the catch.

Havingthus described my invention, I claim as new and desire to secureby Letters Patent 1. In a fastener for a sash, in combination, a casinghaving an opening and adapted to be 3 and I I pro attached to the sash,a pivoted lock adapted to be attached to the sash-frame, and means forpivotally supporting said lock above its center of gravity, said lockbeing adapted to project into said opening to lock said sash.
